''Magnetic capacitance (capacitive magnetic reactance)'' (SI Unit: -Ω−1) is a magnetic "reactance" which prevents magnetic "current" in oscillating magnetic circuits from rising. This is associated with high reluctance. For harmonic regimes it is equal to: : Where: : is the magnetic capacitivity (SI Unit: -s·Ω−1) : is the angular frequency of the magnetic circuit In complex form it is written as an imaginary number: : The electrical potential energy sustained by magnetic capacitivity varies with the frequency of oscillations in magnetic fields. The average power in a given period is equal to zero. The magnetic capacitance is a reactive part of the magnetic circuit.〔Pohl R. W.
